1 Claim. (Cl. 22038.5)

tainer with a screw-cap having a means whereby the screw cap is prevented from being inadvertently lost with respect to the container.

I attain this object by a structure wherein a screw-cap is connected with a tube container by means of a flexible cord. According to my invention, a disk having an axial protrusion at the center of the upper surface thereof is rotatably positioned on the upper surface of the screwcap. A covering member having a central axial perforation in its upper end is adapted rotatably on the disk so as to protrude the protrusion upwardly through said perforation, the skirt of said covering member being fixed on the skirt of said screw-cap. The cord is anchored on a suitable portion of the body of the tube container at one end and secured to the upper end of said protrusion at the other end, whereby said cord is prevented from twist when said screw-cap is rotated.

For a better understanding of my invention and to show how it may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which:

Figure 1 is a front view of an embodiment of this invention;

Figure 2 is a top view thereof; and

Figure 3 is an enlarged vertical section of a screw-cap and related parts.

Similar numerals refer to similar parts throughout the several views.

Referring now to the drawings, a tube container 1 has a mouth 2, a cap 3 being screwed on the mouth 2 as usual. A disk having an axial protrusion 4 at the center of the upper face is set on the upper face of the screwcap 3 rotatably. The disk 5 is covered by a covering member 6 having an axial perforation 7 so as to be adapted to protrude the upper end of the protrusion 4 2,925,935. Patented Feb. 23, 1960 out of the perforation 7. The skirt of the covering member 6 is fixed on the skirt of the screw-cap 3 so as to keep the disk 5 rotatably within the space defined by the covering member 6 and the upper face of the screw-cap 3. The upper end of the protrusion 4 is connected with a suitable portion of the tube container 1 by means of a flexible cord 8 which is anchored on the tube container 1 at one end and is secured on the upper end of the protrusion 4 at the other end.

The covering member 6 may be made of a suitable material such as plastics, metal, paper, and so on. The cord 8 may also be made of a suitable material. It is to be understood that the expression cord is used merely as descriptive and it may be a flexible pipe or a chain.

In operation, the screw-cap 3 may be rotated so as to remove the cap 3 from the mouth 2 or to screw the cap 3 thereon without any rotation of the disk 5 or twist of the cord 8 as the disk 5 may be freely rotated on the cap 3. When the screw-cap 3 has been removed from the mouth 2, the cap 3 is kept in connection with the tube container 1 by virtue of the cord 8 so that there is no fear of losing the cap 3.

While there is herein shown and described a preferred form of my invention, I do not wish to be limited to the form herein particularly shown and specifically described, bu rather intend that the invention shall include all reasonable equivalents thereof which will occur to those skilled in the art from the present disclosure.

I claim:

Means for connecting a screw-cap to a collapsible-wall container to prevent inadvertent loss thereof, said screwcap having a cylindrical periphery and a screw-threaded bore in one end thereof, comprising a cylindrical covering member fitted upon the closed other end of said screwcap, said covering member having an end portion parallel to and spaced from the adjacent closed end surface of said screw-cap and a cylindrical sleeve portion contiguous=ly fitted upon the outer periphery of said screw-cap to rigidly secure said covering member to said cap, the end portion of said covering member having an aperture centrally located therein, a disk element loosely positioned intermediate the end surface of said cap and the end portion of said covering member, said disk being of uniform thickness and having a cylindrical projection centrally located thereon extending through the aperture in said covering member so that said disk may be rotated relative to said cap and said covering member, and a flexible cord connected at one end to the collapsible Wall container and at the other end to the cylindrical projection of said disk.
